BACKGROUND OF THE INVENTION

Embodiments of the present invention generally relate to a spray deviceand particularly to a spray canister device for the delivery of water,medication, solutions and/or a pharmaceutical formulation to a surfacearea of a human subject. More specifically, aspects of the presentinvention provide a method and a wash, clean and dry system with thespray canister device for washing, cleaning, applying water, medication,and/or a cleaning solution to a region of a human body (e.g., skin,genital or anal area, intimate parts, perineal region) and cleaningthereof.

DESCRIPTION OF THE RELATED ART

Bidets and other modern toilet seat systems have been used to spraywater and clean private parts of a user using a toilet. The bidetsystems are used for washing the genital and anal areas using cleaningwater of appropriate temperature sprayed from the center of the bidetsystem, instead of a toilet paper after relief stool or urination.Originally being developed for washing the pubic area of females, bidetsystems are now popular among people of all ages and both sexes becauseit is known to be more hygienic to wash the intimate parts and anus withwater instead of paper after relief. In addition, cleansing thepubic/anal regions with water may help to avoid infection and preventhemorrhoids and other anal disease. Furthermore, it is very effectivefor women with gynecological diseases. It is also very useful for theelderly or obese people to relieve themselves with great convenience.

People who have problems controlling their urine or bowels and sufferfrom incontinence are at risk of skin problems around the buttocks,hips, genitals, and the area between the pelvis and rectum (perineum).Excess moisture in these areas may result in skin problems (e.g.,redness, peeling, irritation, and yeast infections, etc.), and if theperson spends most of his or her day in a wheelchair, or bed, it islikely that bedsores may also develop. Such skin problem may be worse ifthe person uses diapers and other products, which allow urine or stoolto be in constant contact with the skin. As such, special care bycleaning and drying the area right away after urinating or having abowel movement, and/or cleaning the skin with mild, dilute soap andwater then rinsing well and gently patting dry.

In addition, moisturizing creams can help keep the skin moist. Also, askin sealant or moisture barrier, barrier creams or ointments thatcontain occlusive, barrier-type topical, such as zinc oxide, lanolin, orpetrolatum can form a protective barrier on the skin. Some skin careproducts, often in the form of a spray or a towelette, create a clear,protective film over the skin. A doctor or nurse can recommend barriercreams to help protect the skin. There are a wide variety of ointments,creams, barrier sprays, or lotions known and available in the market forthe treatment of diaper rash or incontinence. Most of these productsinclude ingredients that offer some beneficial property to the product,for example, by acting as a skin protectant, water repellant, emollient,neutralizer or antibiotic.

If the individual is alone, applying skin protection paste, ointments,barrier sprays, lotions, solutions, and fluids to an individual's skinis impossible since an individual cannot adequately apply skinprotection fluid onto hard-to-reach areas of his or her own back andbottom. Accordingly, it is necessary to utilize the services of a secondindividual to apply the skin protection fluid on hard-to-reach areassuch as the back and upper neck. Thus, there is a need for using a spraydevice, which applies barrier materials, medicated solutions, fluids,protectants, suspensions, or paste to the skin area of a person, to beincorporated into a bidet seat cleaning system having a water spraynozzle for washing and cleaning private parts of the person.

SUMMARY OF THE INVENTION

The present invention generally provides a method and a wash, dry,clean, and protect system that is easy to handle for washing, drying,and the delivery of water, medication, cleaning solutions, moisturizingcreams, skin sealant, moisture barrier, medicaments, and/or apharmaceutical formulation to a surface area of a human subject. In oneembodiment, a wash and dry system is provided and includes a toilet seatassembly, a spray canister device inside a housing of the toilet seatassembly, and a spray nozzle assembly inside the housing of the toiletseat assembly. In another embodiment, the wash and dry system furtherincludes a medicine delivery assembly.

The method includes positioning a wash and dry systemnear a surface area of a subject, where the wash and dry system includesa toilet seat assembly comprising a housing, a spray canister deviceinside the housing, and a spray nozzle assembly inside the housing. Themethod further includes washing the surface area of the subject usingthe spray nozzle assembly, and applying a spray delivered from anopening of the spray canister device onto the surface area of thesubject.

In one aspect, the method further includes, optionally, cleaning thesurface area of the subject using a cleaning solution sprayed from thewash and dry system. In another aspect, the method further includesdrying the surface area of the subject using a dryer assembly of thewash and dry system.

In one example, drying the surface area is performed by the dryerassembly at high power prior to applying the spray delivered from thespray canister device. In another example, drying the surface area isperformed by the dryer assembly at low power after applying the spraydelivered from the spray canister device.

Further, the method may also include installing the spray canisterdevice into the housing of the toilet seat assembly prior to using thewash and dry system. In one example, the spray canister device isinstalled by gripping a handle grip of the spray canister device andpositioning the spray canister device into a cover of the housing of thetoilet seat assembly. In another example, the spray canister device isinstalled by coupling a trigger bar of the spray canister devicesecurely onto a delivery rack inside the housing of the toilet seatassembly.

In another embodiment, the method may further include shaking the spraycanister device by moving the spray canister device inside the housingof the toilet seat assembly. In one aspect, shaking the spray canisterdevice is performed prior to applying the spray delivered from the spraycanister device.

In still another embodiment, the method may further include applying thespray by moving a canister element of the spray canister device againsta sleeved cover element of the spray canister device along a deliveryrack inside the housing of the toilet seat assembly.
